Commit4445e16bfachanged the signature of esxConnectToHost and esxConnectToVCenter by replacing the esxPrivate pointer with virConnectPtr. The esxPrivate pointer was then retrieved again from virConnectPtr's privateData. This resulted in a NULL pointer dereference, because the privateData pointer was not yet initialized at the point where esxConnectToHost and esxConnectToVCenter are called. This was fixed in commitb126715a48that moved the initialization of privateData before the problematic calls. Simplify the logic by making the call to esxFreePrivate unconditional and changing esxConnectToHost and esxConnectToVCenter back to take a esxPrivate pointer directly. This allows to assign esxPrivate to the virConnectPtr's privateData pointer as one of the last steps in esxOpen making it more obvious that it is not initialized during the earlier steps of esxOpen.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
